1. Patients don't know enough about the disease: when they go to the hospital, they don't know enough about their own disease, which leads to the inability to correctly evaluate the severity of the disease. In this case, the doctor will think that the patient needs hospitalization to prevent the disease from worsening or complications.
2. Students want patients to get better treatment: doctors will choose the most suitable treatment scheme according to patients' condition and needs, and hospitalization is a better choice. For example, patients need to closely monitor the changes of their condition and perform complex surgery or special treatment. Doctors will actively persuade patients to be hospitalized to ensure that patients get the best treatment and care.
